Question

13) y = 4x - 3 -8x + 6y = 14

Answer 1

`\begin{gathered} y=4x-3 \\ -8x+6y=14 \end{gathered}`

Replacing y in the second equation

`\begin{gathered} -8x+6(4x-3)=14_{} \\ -8x+24x-18=14 \\ 16x=14+18 \\ 16x=32 \\ x=(32)/(16) \\ x=2 \end{gathered}`

Then

`\begin{gathered} y=4(2)-3 \\ y=8-3 \\ y=5 \end{gathered}`

Just checking our answer

`-8(2)+6(5)=-16+30=14`

So the correct answer is x=2 and y=5
